Location of biomagnetic activity sources in the brain during acoustic stimulation

It is shown that spectral correlation analysis of magnetic field of human brain can be used to solve the problems of functional neurophysiology: mapping of the brain areas involved in the solution of certain higher nervous activity tasks (perception, processing of external stimuli, etc.). Location of sources of biomagnetic activity in human brain was carried out during acoustic stimulation. The resultant iterative location procedure converges to the true coordinates and amplitudes of sources and provides location at accuracy of 2-5 mm.
